Use and Care Manual
The General Care and Cleaning of Any Copper Sink
Copper sinks are available in a wide variety of forms. They are designed in the apron style, as vessels on the countertop, 
for undermounting, topmounting, and even with options to be installed in several ways. For general maintenance, all 
can be regularly cleaned with a mild detergent, warm water and a soft cloth. Wiping down and drying any sink after each 
use is the best protection against hard water creating blemishes which may become difcult to eliminate. For a thorough 
cleaning after extended use, or to remove stubborn stains, follow the instructions below.
Copper
PATINA 
Copper changes and evolves with time as it reacts 
with the environment. While a new copper sink will 
add beauty and style to any decor, the natural 
oxidization process, or patina, requires some 
attention in order to be maintained. 
SANITIZATION 
The best way to clean a copper sink is with a solution 
of mild soap and water, followed by a wipe-down with 
a soft cloth. Avoid using copper cleaners on your sink 
as they can be abrasive; scratching the surface and 
distorting the patina. 
WATER SPOTS 
If you have hard water, you will want to keep your cop-
per sink clean and dry to avoid water spots. Clean it 
regularly with a mild, non-abrasive cleanser and wipe it 
dry with a soft cloth after each use.

POLISHING AND WAXING 
To help protect your copper sink from hard water min-
eral damage, a wax such as Renaissance Wax
® 
can be 
applied periodically. This will help maintain the luster 
of your sink, however, the use of wax will temporarily 
stop the development of the natural patina. 
We do not recommend polishing a copper sink with an 
abrasive substance or material, as vigorous scrubbing 
can strip off the natural patina.
ACIDIC FOODS and HYGIENE PRODUCTS 
DO NOT leave acidic foods such as oranges, lemons, 
vinegar, pineapple or tomatoes sitting in a copper 
sink. Likewise, in the bath, avoid leaving toothpaste, 
shave cream, or lotions in contact with the sink. Acids 
in these substances could cause shiny spots or dis-
coloration in the sink. Simply clean the area with soap 
and water if contact occurs. Over time, the patina 
will recover and the spot will blend into the sink. To 
avoid this reaction, run water in the sink while work-
ing with acid-based materials and clean immediately 
afterward.
